can someone help me with this question? let z = F(x, y) = x^2 -y +1 b)find the functions g(x,y)= f( f(x,y) , y) and h(x,y)= f(x, (f(x,y) ) c)If f(x,y)= f(y,x) and x cannot equal to y show that y= -x -1

a f( f(x,y) , y) = b f(x,y)= f(y,x) since x - y is not equal to zero, we can divide equation by x - y
